To all whom it may concern:

Be it known that I, EDwAnn WALTER WHITEMAN, engineer, a subject of the King of Great Britain, residing at Dixon House, 72 Fenchurch street, in the city of London, England, have invented certain new and useful Improvements in Machines for Hooping Casks and theLike, of which the following is a specification.

The usual method of trussing and hooping casks is to assemble the staves on the plunger of a machine called a bell. This bell holds in grooves in its inside trussing hoops made of thick rounded metal. As the plunger rises the staves are forced upwards into these trussing hoops and the bell is thenopened leaving the trussing hoops on the cask. The permanent hoops of thin metal are then put onby hand and secured to the casks and the temporary trussing hoops are then knocked off.

All attempts at hooping in the bell that is, putting on the permanent hoops in a bell without the aid of temporary trussing hoops, have failed, mainly for the reason that the upper ends of the staves, as they rise into the bell, frequently catch against the lower sharp edges of the thin hoops and crumple them up. British Patent No. 18,198 of 1905 attempted to overcome this difficulty by rolling or flaring outwards the edge of the hoop which is opposed to the end of the staves as they are inserted into the bell, but this increased the expense of manufacturing the hoops and when on the casks the flared edges of the'hoops protruded and were liable to catch in and tear whatever they came against.

By my invention I am enabled to support the permanent hoops in the bell and to apply them to the cask without using heavy trussing hoops and without making the hoops with a flared edge. For this purpose rings are provided with specially shaped grooves for containing the hoops such rings being constructed in sections wholly or partly of non-magnetic material and are fixed in suitable grooves in the cone and magnets (electro or permanent) are so fixed that the ends of their poles are in such a position as to be near or in contact with the hoops when placed in the rings the hoops being thus held in position in the rings. Arrangements are made to insure that all or nearly all the lines of force pass through parts of the hoops either by constructing the cone and the rings wholly or partly of non-magnetic material or by providing sufficient gap between the magnets and cone to prevent such magnetic leakage into the cone. It is generally only necessary to employ magnets round one half of the circumference of the cone.

To facilitate the placing of the hoops into position in the rings supports are provided which may move horizontally with their top edges in line with the bottom of the grooves in the rings and are so arranged as to be pushed back flush with the inside of the cone when the cask is pressed up and are returned to their normal position by springs or other means.

In order that the invention may be clearly understood I will now particularly describe it with reference to the accompanying drawings.

Figure 1 is a part outside elevation and part sectional elevation of the cone of a hooping machine. Fig. 2 is a sectional plan on the lines AA BB Fig. 1. Fig. 3 is an enlarged part section on the line C-O, Fig. 2, showinga magnet with a corrugated iron hoop in position in its groove. Fig. 4 is an enlarged part section on theline D-D, Fig.2, showing a support with a plain iron hoop in position in its groove.

a is the cone with one half opening on the hinge b and as arranged with two rings 0 with specially shaped grooves 11 for containing the iron hoops e'but any required number of rings may be provided according to the number of hoops to be used. Electro magnets f are provided in each ring and are so arranged that their poles g are near or in contact with the hoops and that all or nearly all-the lines of force pass through thehoops when these are placed in position.

To facilitate the placing of the hoops into position in the grooves d I provide supports h moving horizontally with their top edges in line with the bottom of the grooves and so arranged as to be pushed back flush with the inside of the cone when the cask is pressed up and returned to their normal position by springs 9' or other means.

I claim l. The combination in a hoop-applying machine of the cone provided with a groove adapted to hold a thin metallic permanent hoop practically flush with the inner surface of the cone and magnets arranged outside the groove but in proximity thereto to hold the hoops in position.

2. In a hoop-applying machine the combination of a ring of non-magnetic material having a groove adapted to hold a thin metallic permanent hoop practically flush with the inner surface of the cone and a series of magnets arranged around the ring and adapted to hold the hoop in position.

3. In a hoop-applying machine the combination of acone, a ring therein of noamagnetic material having a groove adapted to hold a thin metallic permanent hoop practically flush with the inner surface of the cone and a series of magnets arranged outside the groove of the ring but in proximity thereto and adapted to hold the hoop in the ring.

4. In a hoop-applying machine the combination of a ring of non-magnetic material, having a groove adapted to practically flush with the inner surface of the cone, a 10 hold a thin metallic permanent hoop practically flush with series of magnets arranged around the outside of the the inner surface of the cone a series of magnets arranged groove and adapted to hold the'hoops in position and :1 around the ring and adapted to hold the hoops in'position series of spring supports adapted to facilitate the placing and a series of spring supports adapted to facilitate the l of the hoops in position.
